It''s a typical 12 volt lead-acid battery discharge characteristic and it shows the initial drop from about 13 volts to around 12 volts occuring in the first minute of a load being applied. Thereafter, the discharge rate doesn''t unduly affect the output voltage level until the battery gets quite depleted of stored energy.
Current research on lead-acid battery degradation primarily focuses on their capacity and lifespan while disregarding the chemical changes that take place during battery aging. ... Before each experiment, the battery capacity was verified through constant discharge at 1 A (0.1 C) to the cut-off voltage of 1.8 V, as indicated by the Chinese ...
The discharge state is more stable for lead–acid batteries because lead, on the negative electrode, and lead dioxide on the positive are unstable in sulfuric acid. Therefore, the chemical (not electrochemical) decomposition of lead and lead dioxide in sulfuric acid will proceed even without a load between the electrodes.
